dsx自动检测出现错误

slist.1.cpp练习完成后进入下一个检测，xmake会报错，然后退出检测，后续继续自动检测也同样报错
报错信息如下
Homepage: https://github.com/d2learn/xlings
error: wait events in poller failed!
error: execv(xmake xlings --project=. J:\cpp_project\d2ds d2x checker) failed(-1)

dustchens

xlings版本为0.0.4

dustchens

退出前xmake build在高速运行

SPeak

可能是msvc构建的时候卡住了. 这个问题是必现, 还是偶现啊

尝试更新d2ds最新代码, 然后使用xlings安装mingw工具链看是否能解决

1.更新d2ds到最新的代码
2.安装mingw/gcc

 xim --update index
 xlings install mingw-w64

3.重新测试验证d2x checker

https://github.com/d2learn/d2ds/commit/f7de9275b958d72267cece7d1055729985501c34

dustchens

@SPeak 貌似还是在这个地方失败了

重新下载了文件后依旧只能执行到slist.1.cpp这一个，后续的无法检测，在我这边貌似是固定复现

SPeak

@dustchens 麻烦做以下两个验证

1.在.xlings目录运行报错命令看是否也会报错(如果报错把报错贴一下报错信息

cd .xlings
xmake xlings -D --project=. J:\cpp_project\d2ds d2x checker

2.先删除slist.1.cpp中main函数中的其他代码(只保留D2X_WAIT), 然后看是否会报错

cd .xlings
xmake xlings -D --project=. J:\cpp_project\d2ds d2x checker

3.把百分百可以复现问题的代码提交到你fork的仓库, 并贴一下链接我也尝试测试一下

SPeak

另外d2ds的最新版本, 下面的乱码应该没有了吧

删除main之前在 .xlings里执行命令的完整输出

xmake xlings -D --project=. J:\cpp_project\d2ds d2x checker

观察了一下xmake build，结束slist.1.cpp 要运行下一个的时候，cpu占用率迅速提升了，本来只有5-6这样，然后提升到了18，然后等待一段时间，大概十几秒二十秒，结束的时候内存占用从60mb突然提升到200多然后结束

dustchens

@SPeak 乱码确实没有了。
是运行下一个检查没有成功，是否需要改slist.2.cpp里的内容？还是我把 .gitignore删掉上传全部内容？没有用过xmake，是不是我自己的代码出现了问题导致的这后面的运行不起来。。我在修改slist.2.cpp里的内容，看看注释掉一部分后哪里有问题，定位到导致出错的语句，然后贴上自己SLinkedList.hpp里的代码，这样可以吗？

SPeak

@dustchens 按你这样描述可能问题时 slist.2.cpp, 你可以试一试把这个里面只留一个D2X_WAIT看看呢, 然后你给一下你仓库的链接我这里也测试一下

测试前运行一下下面命令更新一下, 就直接用d2x checker 就可以了(不用手动到.xlings运行

xlings self update

dustchens

@SPeak 大概定位到了问题，在我当前的代码下，slist.2.cpp里的 // d2ds::SLinkedList<int> intList2(intList1); 这些拷贝语句都会使得无法进入该练习
https://github.com/dustchens/my-d2ds/tree/main/dslings/exercises/linked-list
这是我出错的仓库链接

SPeak

@dustchens 通过分析, 发现主要是程序中存在死循环, 导致程序卡死

死循环位置: 链表析构
原因: 对象拷贝语义未实现 (练习要求实现的
解决方法: 在分配器释放时, 如果异常立即退出程序, 避免crash导致检测中断

具体改动: https://github.com/d2learn/d2ds/commit/92275563edf26c1c413f50fa1b0fc542d94e24ec

尝试更新d2ds代码, 然后测试下是否还有这个问题

dustchens

@SPeak 感谢大佬，已经解决了。不过我还是很疑惑，vector练习里也有自赋值的检测，为什么可以正常进入练习，也只是提示double free，为什么循环链表这里会出现死循环

SPeak

@dustchens 链表结构损坏, 不闭环了 (如果问题解决可以把帖子状态设置为已解决
